It is not so clearcut to attribute the above-average water temperatures off of Baja and California to the current El Nino. Sometimes warmer than average water appears off those coasts after an El Nino has been around for 3-6 months, such as during the summer following an El Nino that peaked the previous winter. Last winter we did have a borderline El Nino, but it's hard to point to that as the cause of the warmth off the mid-latitude North American West Coast. It seems more reasonable to watch for warm waters there NEXT summer, assuming that we have a significant El Nino event this coming winter. Another possible association with your warm waters off the SW US coast could be the Pacific Decadal Oscillation (PDO), which may be beginning to be in positive phase now, following 15 or so years in mainly negative phase from 1999 to 2013. But it's hard to be sure it has switched to positive phase before waiting another year or two to be sure. The PDO has a signal in the water temeprature off of California. As for more tropical storm activity in the eastern North Pacific this summer and fall, yes, there is an established positive association with El Nino. Getting rain in July in southern California has been an extra bonus, though, as even in the most active years for tropical storm activity it is an extreme rarity!
